A successful round of this magnitude is just another notch in the belt for social gaming companies that have seen enormous success in the past couple of years. Several dominant social gaming companies have essentially found ways to print money with the sale of virtual goods.

With OMGPOP’s most recent round of fundraising, there’s clearly no lost interest in the casual and social gaming market. After integrating its games into Facebook — the same route Zynga and others have gone — its player base has doubled from 3 to 6 million, according to the report.

The New York, N.Y.-based company has so far raised $6.5 million since its founding four years ago, according to the report. OMGPOP operates games like Pool and Checkers, and most were free-to-play before the company decided to shift to a freemium model like Zynga and other social gaming companies.
